We replaced our iDevices outdoor plug which finally stopped working after a few years of annoying behaviour. This took about 2 minutes to setup. Plugged it in and within seconds of connecting to it's built in wifi, Apple Home prompted me to "setup and add to home". After a minute, it was done and working.
It's great that both plugs are separate accessories as we have giant outdoor inflatables and lights for decorations. The inflatables are on a separate extension cord so we can turn them off if it's windy but keep the lights on.
